To think you can stay friends with an ex?

[lastnicknamefree]

I feel like it's going well moving from BF/GF to friends but everyone I know is telling me you absolutely cannot be friends with someone you probably still fancy and have been in a relationship with.
We still get on really well without the complications of a relationship and ok still have feelings for each other but we know it doesn't work romantically because we're totally incompatible on that level.
Due to us being together 2 years and being close to each others kids, we've all hung out a few times on a friendship basis and yesterday went to Chessington together. It's been great! I'm happy, kids are happy and I don't see an issue. An I being totally naive? Has anyone else stayed friends successfully?

I don’t think you’re naive.

We’re still friends 5 years in - far easier to do things amicably especially when there are kids involved!

Yes one of my best friends and God father to one of my children I used to be in a relationship with for about a year

Thanks both! Good to hear. I've had nothing but negatively so it's great to have a few alternative stories. I don't want to be in a relationship with him for various reasons, but still care very much and he feels like family. I still want to be in his life, and him in mine. Most importantly, my son's adores him.
Just second guessing after all the horrified comments from friends and family!

Still friends with my exH. Been out for drinks and dinner etc (inc with my dp). He asked for advice on dates, clothes, relationships and I am happily help.
Just because we didn't work out in a relationship doesn't mean he's a bad person (although hes an ex for a reason and does drive me mad with something or other on a weekly basis).

I'm still friends with my ex, my DH is still friends with his ex. In fact we ended up with each other's partners! We did a real life wife swap and still dine together and get on like a house on fire!

Just to confirm, we didn't do this conciously, I started dating my now DH and introduced my ex to his ex. We're all lovely people and are much better suited this way round!
